The approved form of construction coinprises a conduit in the form of a housing 20, having ports 21 and 21 disposed at opposite sides and communicating with the interior of the housing 20. -Flanges 22, preferably made integrally with the housing 20, surround and project outwardly from the ports 21 and 21. The housing 20, is open at one end 23, and interiorly threaded to engage the threaded surface of a cap 24, which is adapted to close the open end ofthe housing- 20. The cap 24:, has a laterally projecting flange 25 which is adapted to seat upon the wall of the'housing 20, and tightly engage the same.

Projectingfrom the interior surface of the cap 2%, is a post or pin 26 and projecting inwardly from the inner surface of the closed end 27 of the housing 20, is a pin or post 28 which is preferably made integral with the wall of the housing 20. These pins 26, and 28 project inwardly from the center of p the end and the cap and are spaced apart at their inner ends. A curved metallic valve 20,'the periphery of which is struck on a circle having the same diameter as the interior surface of the housing 20, so that the member 29 may lie in engagement, throughout its entire surface, with the inner surface of the housing 20. Projecting inwardly from the opposite ends of the mem-- ber 29, are arms 30, which may be connected to the same by being formed dovetailed and secured in a dove-tailed slot 31. Positioned rotatably upon the pins 28 and 26 are arms 32 which, project outwardly and are securely fastened to the inwardly projecting arms 30,

by means of bolts 33. Each of the arms 32 is provided with aslot in which one of the bolts 33 may be permitted to ride. As clearly shown 1n Fig. 5, the arms 32 and overlap. Therefore, it appears evident that upon tightening the bolt 33, which is threaded into the member 30, the arms 32 and 30 will. be retained in immovable relation to each other. The purpose of this connection the housing 20, the adjustments being made whenever the necessity a ises from wear of the parts involved.

Interposed between the under surface oi the lower member 32, and the inner surface of the member 2%, upon the member 26 is a spirally formed torsional spring 34, one end of which engages a stop block which projects from the inner surface of the member 2d. The other end 37, of the member 3%, engages a stop block 38 which is the head of a pin 40, which is inserted through the member 32 and extends upwardly so as to engage between the teeth of a. 39, which is rotatably mounted upon the member 26, so as to engage the upper surface of the member 32. A retaining member ll, which is formed tubular at its opposite ends eniibraces or receives the inwardly projecting ends of the members 26 and 2S, and thereby retains the inner ends of the memhere 32 in their spaced relation. Projecting laterally from the central portion of the member 1, is a post upon which is positioned one end of a spiral spring as, the opposite end of the member being positioned upon a post l-fi, which projects inwardly from the inner surt cc of the incur ber 29. The purpose of the spring s3. is to afford a means of adju the member 20 upon release of the traction between members 32 and lhe spring 43 serves to push the member 29 outwardly so that when the member 29 is adjusted so that it is'not spaced its maximum distance from the member 41, the spring -13 will be compressed.

Projecting inwardly from the inner surface of the ca 3 24:, adjacent one side there of. is a cup shaped member 45, an opening 45 being provided in the member 24, registering with the cup member Project ing through the inner surface of the member L5. is a bolt 46 which is adapted to be secured in its assembled position to a gear wheel l8, which meshes with the gear 5% Projecting outwardly from the member 48, is a cup shaped member Securely f tened within the c .p shaped member 45. by means of a bolt this a guard or tumbler 50, this tuu'ibler being adapted to extend into the opening 14-5. in the member cup or barrel 51 is provided. which is adapted to seat in the opening l5. which is formed in the member 2% A key hole is provided int-he member 5i for the in sertion of a key therein. w iich is adapted to engage in a recess. Formed in the cup shaped member 19 and thereby atiord a means of rotating the 4:8. 7 ber 51 is secured in its assen'ibled posit; in the opening 45' by means oi? a bolt 53, which is threaded into the member 5i and adapted to slidably engage in slot 51-, formed in the member 45 adjace .t the inner surface of the cap 2%.

Threaded into the housing 20, is a nipple engage,

55. which is open at its inner end. Mounted thin the nipple 55, is a rod 56 which projects through an opening in the wail of the housing 20, and extends into the interior thereor. Securely mounted upon the member 58, adjacent the inner end tl eree'l and within the nipple 55. is a collar 57. Positioned upon the member 56. within the nipple 55, and interposed between the end of the nipple 55 and the collar 57. is a spiral spring 58, as clearly appears from Fig. 6. Upon withdrawing the member 56 from the housing 20, the spiral spring will force the member 56 back into the housing 20, upon release of the withdragving force. providing trigger mechanism in the :lorm oi a catch which will engage the valve member 29 when the same is turned to open position.

As is clearly shown in Fig. l. the rod 56 is provided with a flexible meml'ier. such member to extend to a convenient position with respect to the drivers seat tor releasing the catch for permi ting the closure of the valve.

Formed adjacent one end of the mi'zn'i )6! 29., at one edge thereof is a recess 59, (Fig. 6) in which the member 56 is adapted to when in operative position clearly seen in 5. Projectinginwardly through the wall oil the housing 20 and ex tending a distance into the interior, a stud 60, which adapted to the member 29 when the-same is moved to 0; eratire position, or to that position in which the lower port 21 is closed (see Fig. '3).

Mounted upon the inner Face of the member 2st, is a pawl 61, with which cooperates a spring =32 also mounted upon the member The member 62 has a tendency to r tain the member 61 in outwardly extending position. Formed in the inner surface of the member 20, adjacent the end on which member 2%: secured. are recesses (33, in which the pawl 61 is adapted to engage when projecting outwardly. The construction is such that upon the turningon of the cap 2i. the pawl engages agaii'ist the interior surt'aceot the member 20 and flexed inwardly so as to be in recess (34. formed in the cap 2- Upon the member 61, passing the recesses 63. the pawl "ill respond to the tension of the spring 62 and engage in these recesses. It is thus seen that upon the threading on of the cap 24, the same cannot be removed by backward threading without first turning the pawl. into the recess 64;. To do this. it is of course necessary to operate in the interior oi the housing 20, through either of the ports 21 or 21. The manipulation of this pawl or a turning ot either of the gear wheels 39 or d8, is "further rendered difiicult by the pres ence of a disc 65 which is mounted upon the member 4:6 and retained in posinm by a nut 66. An opening is provided centrally buretor 67 and the intake pipe 68 of the manifold of the engine. My invention is adapted to close communication between the carburetor and the intake pipe of'the mani told and securely lock the same in such closed relation until a key specially designed for the particular device used is inserted in the keyway for opening communication between the carburetor and manifold. v

WVhen the communication is established between the carburetor and manifold, the port 21 will be open and the member 29 will be in the position shown in Fig. 5,,and it 7 will be noticed that the member 56 is there shown engaging the member 29 in the slot 59. In order to place the member 29 in this position, it was necessary to rotate it 90 degrees approximately, within the housing 20. The member 56 automatically engages in the opening 59, upon the rotating of the member 29 a suflicient distance. Upon disengaging the member 56 from the member 29, the member 29, responding to the strain exerted by the spring 34, as shown in Fig. 6, will quickly move in the direction indicated by the arrow, and thereby close the port 21. The member 60, is provided for -the purpose of preventing't-he member 29 from moving beyond the opening or port, as will be readily understood. 1

When the device is assembled upon the engine and the valve 29 has moved to clos ing position, a key is inserted in the key hole 52. Each particulardevice is specially constructed so far as the tumbler is con: cerned and consequentlyhas itsnownindividual key. The key of course turns the member 51, and also engages the member .49 and thereby rotates the gear 48, which in turn rotates the gear 39, which carries with it the lower arm 32 and thereby movesthe' valve 29. I have shown myinvention applied to a gasoline engine and disposed in-: termediate the carburetor and the manifold. However, my device may be applied to a gasoline engine at any suitable place intermediatethe manifold and gasoline supply tank. I "1 In the'modified torm (Figs. 11 to .19) I provide a pair of valves,-which are connected together and operate simultaneously. One of the valves, that, is'the outer. valve disposed. in a slot (Fig. 17) whichis formed in the wall of the housing 20. O1 course, in the devices inwhich the slot 70 (Fig. 17) appears, the wall of the housing ismade thicker than otherwise. The outer valve 70, which rides in the slot70 (Fig.

17), is connected to the inner valve 29 by connecting means comprising a bolt 72 (Fig. 19) threaded into the valve The form a cup 71 in which is positioned ahead .74 of a bolt 73, which is threaded into the valve29, a recess being provided in the inner end ofthe bolt 78 for affording a means of'turning the same with a screw driver or other like instrument. Positioned in the cup 71, and engaging the inner face of the. member 74, is a spiral spring 75. It is apparent that the pressure oithe valve 70, against the outer wall of the chamber in which it rides, may be regulated by adjustment of the member 73. A slot 76, is provided in the inner portion of the wall of the housing 20 in which the connecting means joining the two inner end of the bolt 72, is constructed to valves is adapted to slide. 2 The valve 29, is

connected to the valve 70 at two'ends ad- .jacent one of the sides by the means already formed thereon, adapted to engage in re-.

cesses formed in the, inner wall of the housing. In the modified form, adjacent the cap 24, I have secured to the inner wall of the housing 20,a leaf spring 78, which is adapted to be flexed upon the opening of the valve and consequently under strain to restore the valve to closing position. This spring 78, may be used either separately or in conjunction with the spiral spring 34:.

In my modified form, Ihave provided a device which will be effective even though one of the valves should leak, as the additional valve aiiords a secondary safeguard. The valve, which I have shown in the modifiedform, may be used generally wherever an instantaneously closing valve'may be required; This feature of this valve is apparent inasmuch as the valve instantly closes upon retracting or withdrawing the member 56 from engaging position with the valve. In Fig. 17 the member 56 is shown as engaging both the valve 70 and the valve 29. I

While I have illustrated and described the preferred forms of constructionfor carrying my invention into effect, these are capable of variation and modification withvariations and modifications as come within the scope of theappended claims.
